Hello justine ,
First of all , for saving some time , you can just download this Data File and then exctract it on the InfinityMu Folder :

However , you can just re-download the client or if you already have the client you can just re-install it .

But if you want some help with the anti-lag , I can just show you what to change with the anti-lag patch and you will not have any problem . I think you want to show up wing's or combo or buffs , just let me know what do you want to see .
Thank you , if you need any other help you can just tell us
